You can restrict access to tables by business organizational units using the line-oriented authorizations introduced in release 4.6C. You could previously only use the authorization objects S_TABU_DIS and S_TABU_CLI to allow or prevent access to complete tables.
The introduction of organizational criteria allows you to restrict user access to parts of a table. The authorization object S_TABU_LIN has been introduced for this purpose.
One possible use for line-oriented authorizations would be that a user can only display and change the contents of a particular work area, e.g. a country or plant, in a table.
